I'm working with a dataset in a data warehouse. It is a very large dataset but I suspect in most cases the users will only be querying newer data. I think a Direct Query solution will likely work, but I wondered what the best place is to put in my date filters would be. Is it better to insert these filters at the Power Query level or in Power BI? Or does it matter since the queries are only actually sent when a visualization is refreshed?
Theoretically, then, I could insert a report-level filter for dates and have that set as default but allow report viewers to change it if for some reason they want to query older data? In most cases that should keep performance within reasonable bounds, right? If that works, it seems like a nice compromise.
